I saw a program recently called "How the Universe Works" discussing Black Holes. One of the enigmas, it seems, is the existence of extraordinarily large 'supermassive' black holes -- black holes of hundreds of billions of solar masses. They were thought not to be able to have formed organically given the age of the universe -- or so the program stated.
The theories discussed for the formation of such black holes had to do with the improbability of forming from such masses of early hydrogen, or the consumption of other matter/black holes since the Big Bang. Evidently, there would not be nearly enough time for such supermassive black holes to form.
It occurred to me that there may be another way for these monsters to appear. We know that the universe was not homogeneous even at the beginning by looking at the cosmic background radiation. The density and distribution of the galaxies and galactic clusters throughout the universe seems to follow suit. So, why could these supermassive black holes not have formed more quickly in the beginning when the energy/mass densities were the highest they would ever be?
One analogy comes to mind is super cooling. I could imagine the early universe in whole or in part in a very exotic unstable state such as a super cooled liquid. Any anomaly or perturbation could nearly instantaneously 'condense' or nucleate an incredibly high local energy density into it's matter counterpart. I imagine this happening even before the formation of neutrons/protons/electrons or other matter -- perhaps on a scale to produce one of these enigmatic black holes.
Since we already have matter-antimatter pairs appearing out of the energy of the vacuum, then annihilating, this idea did not seem so far-fetched. Perhaps others have considered such a possibility.
